水稻是一年生禾本科植物,喜高温、多湿、短日照,对土壤要求不严,水稻土最好。穗分化至灌浆盛期是结实关键期;营养状况平衡和高光效的群体,对提高结实率和粒重意义重大。1.栽培技术1.1培育壮秧由于旱育苗床的培肥效果和控水效果,导致床土容量和含水量降低,空隙度增加,含氧量提高,对幼苗生长发育十分有利,稀播才能育成壮秧,壮秧返青快,分蘖早,为水稻高产打下基础。1.2育苗(1)苗床地的选择:选无污染,背风,向阳,水电源方便,地势高,干
Rice is an annual gramineous plant, like high temperature, wet, short sunshine, lax requirements of the soil, paddy soil is best. Spike differentiation to grain filling is the critical stage of critical stage; nutritional status and high luminous efficiency of the population, to improve the grain yield and grain weight is significant. 1. Cultivation techniques 1.1 Cultivation of strong seedling nursery seedlings due to dry cultivation effect and water control effect, resulting in bed soil capacity and water content decreased porosity increased oxygen content increased, very beneficial to the growth and development of seedlings, thinning to bred Strong seedlings, Zhuang Yang fast green, tillering early, lay the foundation for high yield of rice. 1.2 Nursery (1) seedbed selection: election pollution-free, leeward, sunny, convenient water supply, high terrain, dry
